Denaturation disrupts the secondary and tertiary structure of proteins. However, denaturation is not strong enough to disrupt what interaction that is relevant to protein structure?.
Denaturation is not strong enough to disrupt the primary structure interaction that is relevant to protein structure.
What is Denaturation?This is the process in which weak linkages which make a protein structure to be highly ordered are broken.
Denaturation is mostly caused by heat and isn't strong enough to break the peptide bonds which are responsible for the primary structure and helps it t maintain the amino acid sequence.

As a general rule, _____, which transport water in _____, have a potentially higher transpiration rate than _____, which transport water in _____.
The rule is, that the part of the plant which transports water in higher concentration will have a potentially higher transpiration rate than the parts of the plant which transport water in a lower concentration.
What is Transpiration?This refers to the mechanism through which plants intake and evaporate water from and back into the environment.
Please note that water loss occurs most from the leaves of the plants. The stomata of the plant are responsible for controlling water loss or leaf transpiration.

Which of the following is not true concerning cover crops? a. They prevent soil erosion b. They can fix nitrogen in soil c. They are sold as cash crops d. They add organic matter to soil Please select the best answer from the choices provided A B C D.
In the agricultural practices cover plants are grown for the enrichment and the protection of the soil. They are not harvested to be sold as cash crops.
What are the cover crops used for?Cover crops are grown in the agricultural land parts to maintain the soil fertility and quality so that the land will be safe from the invasion and attacks of pests and weeds.
They are generally grown after the reaping of cash crops and help in soil binding by preventing erosion from the water runoffs.
These plants help in fixing the nitrogen content of the soil and help the soil to remain fertile and nutrient-rich. They increase the organic and the mineral compounds to the soil profile and enriches the soil quality.
Therefore, option c. they are sold as cash crops is incorrect.

Fruits and stem have lenticels. Give reason
Answer:
because lenticels permit the exchange of gases between the environment and the internal tissue spaces of the organs
Fruits and stems have lenticels. These are the specialized cells which permit the exchange of gases between the atmosphere and the plant body.
What are lenticels?A lenticel is a specialized tissue which is a porous tissue. It consist of cells with very large intercellular spaces in the periderm of the secondarily thickened organs in the plant body and the bark of the woody stems and roots of the dicotyledonous flowering plants.
Lenticels can be easily seen as they are visible on the surface of fruits, such as mango, apple, and avocado. Lenticels permit the exchange of gases between the external environment and the internal tissue spaces of the organs such as stems and some fruits of the plant body. These cells permit the entrance of oxygen gas into the plant and simultaneously the output of carbon dioxide and water vapor from it.

Your ecology club has decided to write a letter to the editor of a local newspaper about protecting the biodiversity around this new highway project. As citizen- scientists, what factors would you include in your letter to help educate people, including other citizen-scientists, about the importance of preserving biodiversity? thank you for whoever answers!!
Answer:
The factors I would include in my letter to help educate people is that in the niche diversity, a niche could be shared by two different species so they would compete for resources. If they are low, then one species may die out. The importance of preserving biodiversity is because of the natural resources which are often at the root of conflict.

A plant can produce either purple flowers or white flowers. The purple flower color is dominant over the white flower color. What is the ratio of the offspring with purple flowers to the total number of offspring if two plants that are heterozygous for purple flowers are crossed? 1:4 2:4 3:4 4:4.
Answer:
C 3:4 is the answer.
Explanation:
Best of luck to you!
The phenotypic ratio is 3:4 if two plants that are heter---ozygous for purple flowers are crossed.
What is phenotypic ratio?The phenotypic ratio is the ratio of the appearance of the organisms. We know that the phenotype stems from the genotype of the organisms.
Thus, if the purple flower color is dominant over the white flower color, then it follows that the phenotypic ratio is 3:4 if two plants that are heter---ozygous for purple flowers are crossed.
